Because:
- glean_parser <v19 / glean.js <v5.0.8 caused server-side Glean events
to have wildly incorrect timestamps (DENG-10432)
This commit:
- Bumps @mozilla/glean from 5.0.4 to 5.0.8
- Updates glean_parser from ~=14.5 to ~=19.0 in CI and mono Dockerfiles
- Recreates venv with glean_parser 19 in CI provision step and
persists .venv to the workspace to avoid pip uninstall bug that
hits when cached Docker images still have 14.5.2
- Regenerates all Glean code with glean_parser v19.0.0
- Removes orphaned generated files (standard.js, sync.js, webauthn.js)
whose metrics were previously removed from YAML definitions
- Fixes timestamp bug for accounts_backend and
subscription_platform_backend server events
Fixes FXA-13435
